this paper deals with application of polyaniline coated on wood sawdust for removal ofmethylene blue (mb) dye from aqueous solutions. polyaniline coated onto sawdust (termedas pan/sd) was prepared via direct chemical polymerization onto sawdust which waspreviously soaked in the monomer (aniline) solution in acidic (hc1) media. adsorptionexperiments were carried out using batch system. the effec...

backgroud and purpose: dye is one of the problems of industrial effluent such as textile industries. the dyes can be removed by various methods. therefore, the aim of this study was the evaluation of adsorption rate of reactive red 198 from aqueous solution by activated red mud. materials and methods: this research was a lab study. activated red mud was used as an adsorbent to remove reactive r...

Textile dyeing is considered to be one of the major industrial sources of high rates of organic and aromatic compounds. Conversely, these compounds have become a significant environmental problem. Many methods have been investigated for color removal from dye-containing wastewater. In this research, the efficiency of the electrocoagulation (EC) process with aluminum electrodes in the removal of...

background; recently, there has been a great concern about the consumption of dyes because of their toxicity, mutagenicity, carcinogenicity, and persistence in the aquatic environment. therefore, the aim of this study was to determine the feasibility of using lemna minor for acid blue 292 (ab292) dye removal from aqueous solution and to determine the optimal conditions. methods; this experiment...

Natural dye extracted from aerial parts of Barleria prionitis and different kinds of textile fabrics dyed with the natural dye were investigated for their antifungal activity. Antifungal activity of natural dye and dyed fabrics was assessed against standard strains of five fungi namely Aspergillus flavus, A. niger, A. parasiticus, Fusarium moniliforme and Penicillium canescens using agar-we...

Introduction: Textile industries produce large volume of colored dye effluents which are toxic and removal of dyes from wastewater is a significant environmental issue. Advanced oxidation process (AOPs) is alternative method for the complete degradation many organic pollutants. ZnO and TiO2 are important photocatalysts with high catalytic activity that have attracted much research attention. ...

Athi tree leaves (Ficus relegiosa) powder carbon was used as an adsorbent for the removal of DNB-106 dye from an aqueous solution. The studies were carried out under various experimental conditions such as agitation time, dye concentration, adsorption dose, and pH to assess the potentiality of Athi leaves powder carbon (ATC) for the removal of DNB-106 dye from wastewater. A greater percentage o...

The effect of indigo dye effluent on the freshwater microalga Scenedesmus quadricauda ABU12 was investigated under controlled laboratory conditions. The microalga was exposed to different concentrations of the effluent obtained by diluting the dye effluent from 100 to 175 times in bold basal medium (BBM). The growth rate of the microalga decreased as indigo dye effluent concentration increased ...

BACKGROUND Reactive Red 31, applied extensively in the commercial textile industry, is a hazardous and persistent azo dye compound often present in dye manufacturing and textile industrial effluents. Aspergillus bombycis strain was isolated from dye contaminated zones of Gujarat Industrial Development Corporation, Vatva, Ahmedabad, India. The decolorization potential was monitored by the decrea...
